correlational
Showing mutual variation
Correlational describes research or analysis that examines relationships between variables without establishing cause and effect.
A correlational study might find that ice cream sales and drowning deaths both rise in summer—they're correlated, but one doesn't cause the other.
The evidence is correlational, not causal.
The term appears most often in social sciences and statistics.
